Good news Professor Errare fans who also happen to be obsessive compulsive. As some of you have probably noticed, there was a slight change in cover design between the first two Professor Errare books and the last two. This was due to a complicated situation revolving around certain service providers changing the options available on certain programs…..blah blah blah blah blah. Anyways, as a special treat, the good professor has gone back and redesigned the covers to his earlier books so that they can all express a single signature style. Enjoy.
